Diagnosis.

The new species is similar to Lista longifundamena  sp. n. Both species are different from other congeners by the straight postmedial fascia on the forewing; however, Lista longifundamena  sp. n. has the valva slightly constricted from the middle to the apex, the sacculus with the inner processes at middle more slender, and the apex of the juxta bifurcated with two strongly sclerotized slender arms.

Description.

Adult. Forewing length 9.5-10.5mm (n = 4). Head yellow; labial palpus upturned, mixed with yellow and black scales; maxillary palpus pale yellow; antenna pale brown, scape extension black, mixed with golden scales in male. Thorax mixed with blackish-brown and a small number of yellow scales. Forewing covered with brown, yellow, black and pink scales; postmedial fascia straight, pale yellow with brown edges, outer area covered with fuscous and dark pink scales; cilia brown. Hindwing with similar pattern to forewing, but more brown scales than forewing in central area, and outer area covered with pink scales.

Male genitalia (Fig. 15). Uncus broad, densely covered with setae, two spine-like processes at base laterally. Gnathos narrower and more sclerotized than uncus. Valva slightly broader from base to apex, apex rounded; costa slightly sclerotized, apex swollen; sacculus with two processes in middle, the inner one spine-like, the outer one thorn-like, a thin sclerotized plate from sacculus to center of valva. Juxta peltate and bifurcated, apex pointed. Phallus curving slightly, with a crescent-shaped cornutus at apex.

Female genitalia (Fig. 25). Ovipositor slightly narrow, suffused with setae. Apophysis anterioris longer than apophysis posterioris. Ductus bursae slender, membranous. Corpus bursae round, with two signa, nearly oval.
